District heating systems (DHS) have developed as large-scale and very complex engineering structures. In different countries of the world, are used various strategies of their regulation: by quality, by quantity, by combining of quality and quantity. The purpose of the operating conditions development is to find such conditions under which the supply of consumers with the required amount of heat by given quality while observing all the technical and technological requirements. The task of calculating the DHS conditions is to find the distribution of flows, pressures and temperatures across all elements of the design scheme for a given topology, hydraulic and thermal characteristics of its elements and boundary conditions. There are two types of calculation of DHS conditions: adjustment and verification. In article presented DHS operating regime development technology. The “Angara-HN” software can perform the whole complex of calculations.
